G. Ross Roy: A Tribute

Robert Burns & Friends essays by W. Ormiston Roy Fellows presented to G. Ross Roy edited by Patrick Scott and Kenneth Simpson This volume of essays about the Scottish poet Robert Burns (1759-1796) pays tribute to the distinguished Burns scholar G. Ross Roy. Subjects covered include writers who influenced Burns; aspects of the writing of Burns and that of his friends and contemporaries; and Burns\u27s influence on later writers. The volume also includes essays on Ross Roy\u27s own accomplishments and on the Burns collection he built (now at the University of South Carolina), together with a checklist of his published writings. G. Ross Roy, Distinguished Professor Emeritus of English and Comparative Literature, founded the journal Studies in Scottish Literature in 1963, and as its editor for nearly fifty years he has had a central role in establishing international academic recognition for the field. His own scholarly work includes the standard Letters of Robert Burns (2 vols., Clarendon Press, 1985). His contributions to Scottish literature have earned him honorary doctorates from the Universities of Edinburgh (2002) and Glasgow (2009). The contributors are all former W. Ormiston Roy Visiting Fellows at the University of South Carolina. This book is also available in a print edition (ISBN: 978-1439270974) through the usual on-line vendors. It is not available for direct purchase from the editors or the University of South Carolina

Relative value of carotenoids as precursors of vitamin A

The carotenoid pigments are very conspicuous in nature, owing to their yellow to red hues, and occur without exception in photosynthetic tissue. They are responsible for the colour in some species of yeast, bacteria and fungi as well as many vegetables and fruits. Although animals are incapable of de novo synthesis, they are able to deposit the carotenoid pigment as absorbed or with some alteration of the basic structure. Thus, the red to yellow colour in the flesh, skin, shell or exoskeleton of salmon, lobster, crab, prawn, carp, flamingo, etc. is directly or indirectly diet-related. The intestinal cleavage of carotenoids to form vitamin A active retinoids represents the main contribution of the carotenoids to nutrition. The colour associated with foods such as vegetable, fruits, butter, egg yolks, salmon, etc. represents an aesthetics contribution made by these pigments. An inspection of other papers in this symposium demonstrated that the retinoids have a wider application to health than has been traditionally thought. Likewise, recent findings support to suggestion for a wider, non-vitamin A role of the carotenes. The structures of some common carotenoids are shown in Fig. 1 β-Carotene, while not the most abundant carotene is, nevertheless, very widespread in nature. Both halves of β-carotene are related to retinol, thus the compound possesses maximal provitamin A activity. γ-Carotene, with one ring, α-carotene with a 4’, 5’ double bond in the ring, and β-cryptoxanthin (xanthophyll) and β-carotene-5,6-epoxide, with substituted rings, contribute 50% of the activity of β-carotene

Epistolary Performances : Burns and the Arts of the Letter

The letters written by the Scottish poet Robert Burns (1759-17960 show a self-conscious writer, who relished the craft of letter-writing and the role-playing that it allowed him. Examines letters that Burns wrote to Dr. John Moore, Margaret Chalmers, and others, and suggests a kinship between Burns as letter-writer and the letters and novels of Laurence Sterne

Wraiths, Rhetoric, and The Sin of Rhyme The Shaping of the Burns of the Kilmarnock Edition

Discusses rhetorical self-consciousness in letters and poems of the Scottish poet Robert Burns (1759-1796), in contrast to earlier simplified romantic portrayals, and draws a comparison between Burns and Montaigne

Algebraic analysis of Trivium-like ciphers

Trivium is a bit-based stream cipher in the final portfolio of the eSTREAM project. In this paper, we apply the approach of Berbain et al. to Trivium-like ciphers and perform new algebraic analyses on them, namely Trivium and its reduced versions: Trivium-N, Bivium-A and Bivium-B. In doing so, we answer an open question in the literature. We demonstrate a new algebraic attack on Bivium-A. This attack requires less time and memory than previous techniques which use the F4 algorithm to recover Bivium-A's initial state. Though our attacks on Bivium-B, Trivium and Trivium-N are worse than exhaustive keysearch, the systems of equations which are constructed are smaller and less complex compared to previous algebraic analysis. Factors which can affect the complexity of our attack on Trivium-like ciphers are discussed in detail
